Thomas records two circular entrenchments near the houses at Menagissey (SW 712467).

An extant round is listed by Warner (2) at SW 71324667 and the possible remains of two rounds at SW 712467 (3). These rounds are the most westerly of a series of apparently associated earthworks seen by Thomas which ran between Menagissey and Coosewartha (see also SW 74 NE 16, 17, 20). (1-3)
